Gluma脱敏剂预防深龋充填后牙本质过敏症疗效观察

Efficacy of Gluma desensitizer for prevention of dental hypersensitiveness after deep caries filling

目的观察Gluma脱敏剂预防深龋充填后牙本质过敏症的疗效。方法将236例354颗深龋患牙随机分为3组,A组采用常规充填,B组用Gluma脱敏剂+常规充填、C组用酸蚀处理剂+Gluma脱敏剂+常规充填。比较3种方法的有效率。1周、6个月复查。结果C组的有效率明显高于A、B组(P<0.01),A、B组之间无显著性差异(P>0.05)。结论用酸蚀处理剂+Gluma脱敏剂预先对窝洞进行脱敏是预防深龋充填后牙本质过敏症的较好方法。

Objective To observe efficacy of Gluma desensitizer for prevention of dental hypersensitiveness after deep caries filling. Methods Two hundred and thirty- six cases （n= 354） of caries were randomly divided into three groups： group A was performed with routine filling , group B was performed with combination of Gluma desensitizer with routine filling and group C was treated with combination of acid etching agent, Gluma desensitizer and routine filling. Effective rates were compared in three groups. Reexamination was performed after 1 week and 6 months. Results Effective rate in group C was obviously higher than that in group A and B （P 〈 0.01 ）. There was no significant difference between group A and B （P 〉0.05）. Conclusion Pretreatment of acid etching agent plus Gluma desensitizer for desensitization of cavity is better measure for prevention of dental hypersensitiveness after deep caries filling.
